Toall whom t may concern: I

Be i known that we, HOWARD F. MAlsToN and JOHN J. OCoNNnLL, both residing at Dayton, Ohio, have invented certain new and I useful Improvements in VVindow-Envelops,- of which the following is a full, clear, and exact description. j

'This 'invention' relates to improvements iin Window .envelops of a type shown, de-

dicating to the postal authorities that the Y 4ed and ready for the inclosure. Fig. 3 shows the envelop with the inclosure therein, and with the seal iap folded down, and with the.

scribed and claimed generically in our copending application, Serial No. 39,253, filed July 12,1915. I

This particular improvement relates to an envelop which is so constructedzthat the contentsor-inclosure may be inspected bythe postal authorities. Such envelops are carried in the mails at a reduced rate of postage, and are generally .lmown as fpennyv savers on account of the saving of postage incurred through their use.

Our particular improvement consists in so fabricating the envelop that by out-folding one of the flaps the contents may be inspected.

Our envelop also provides a means for inenvelopis unsealed, t'. e. a penny saver and thus preventing the postal authorities' tached, the iiap :being gummedand ready for folding.- Fig. 2 shows the envelop foldcharacters indicating thatthe envelop is unsealed, appearing through the'transparent sheet-forming the front of theenvelop..`

The 'body portion. of the en velop is made yof opaque material. This" opaque portion of the blank comprises the back shown at 10, and defined by the fold lines11, 12, 13

' and 14; second, the side ap 15 deiined'- by fold line 13 and margin line 19; third, the side Hap 16 nwhich becomes thel inspection flap when the envelop blank is folded, this side Hap 16 being defined by fold line 11 and margin line 17 ;`fourt h`, the bottom flap 25 defined by fold line 14 and margin line 24;

' and, fifth, the seal lHap 20 defnedby fold Specication'o Letters Patent.

line 12 and margin line 18. Side Hap 15 and y the seal flap 20 are gummed as shown by the shaded gum strips 33 and 29 respectively.

In making the envelop, the body portion kis cut'to the shape shown in Fig. la Then the transparent sheet 27 is attached by gum to the bottom Hap 25. -This transparent sheet 27 is defined by inargin lines 21, 23,

28, 26 in Fig. 1. The inspection ap 16 is then folded'along fold line 11 over the back portion 10. Thereafter, vthe transparent Osheet 27 is folded along fold line 14 overthe back portion 10' of the envelop. Then side flap 15 is folded -over the transparent sheet 27. and engaged by the gum to said sheet.

During the fabrication of the envelop flap themwords Not fastened, or words conveying a similar-meaning, are printed on the inspection ap 26. These words are printed on the side of the Hap which is uppermost when the side flap is folded under the transparent sheet. The words will then be visible through' the transparent sheet, and will indicate to the postal authorities that the envelop is of the unsealed penny saver type. The words Not fastened are shown at 35 in Figs. 2 and 3.- 4

The complete envelop'is shown in Fig. 2. In this figure it will be seen that the transparent sheet terminates 'at line 26, which is a `short distance'below'the fold line 12. In thisway margin line 26 o f transparent sheet By so arranging the transparent sheet, and by having the side and inspection flap sloping as shown, 1t 1s easy to insert an inclosure in'theenvelop, and the danger of tearing the transparent sheet is minimized.

By referring to Figs. 2 and 3 it will be seen that while an inclosure is being inserted in the envelop, the inscription forming-the For this reason the person inserting the inclosure is less liable to make mistakes, such as placing Vthe letter or inclosure in the-envelop upside down or wrong .side forwar'd.l However,

after the inclosure is properly placed in the 1'05 envelop the seal flap 20 lis folded down and the vgumstrip 29 secures it to the transparent' sheet. This' seal Hap being opaque defines the top of the window and obscures. any

Written matter that may appear above the address or inscription on the inclosure. The sides of the Window are defined by themar gins 17 and 19 of the opaque side flaps 15 f and 1.6., and the bottom of the window is defined by margin 24 of the opaque bottom iap 22.

We claim:

el. An envelop, comprising in eombina.

tion; an opaque back portion; a transparent sheet attached thereto and adapted when folded to terminate at the edge of the pocket and thereby form a transparent front for the envelop; an opaque seal flap engaging the transparent sheet and defining the top I of the window therein; a Hap bent under the transparent sheet but not engaged thereto, whereby the envelop can be opened for inspecting the inclosure without the breaking of a seal.

2. An envelop comprising an opaque back vportion a transparent ifront portion extendl .ing to the edge of the pocket a plurality of side flaps, one flap being engaged by the transparent front portionv and the other being folded thereunder, but not engaged thereto, whereby the contents of the envelop ma be inspected; and an opaque seal Hap which is adapted to define the upper margin of a transparent window when sealed down on the transparent front of the envelop.

3. An envelop comprising an opaque back portion; 'a plurality of side flaps; a bottom flap; a transparent front portion extending to the edge of the pocket and engaging the bottom flap, and one of the side flaps; the

other side Hap being folded under the transparent frontwportion whereby the contents of the envelop'may be inspected, and a seal flap extending over and sealing down on the transparent front of the envelop thereby deining the upper margin of a window in the front ef the envelop.

4. An envelop comprisingmn opaque back portlon; a plurality of iaps extending therefrom;.a transparent sheet engaging two ofi said flaps and'extending to the edge of the pocket thus Y forming a transparent front for the envelop,.the other of said flaps being f extending from the back portion and folding under the transparent sheet; a seal iap folded over and engaging the transparent sheet and defining the upper margin of a window therein; and indicatinglcharacters on the inspection iap and visible'through the transparent sheet toshow that the said envelop is not entirely sealed when the seal flap is secured to the transparent sheet.

6. An envelop comprising -an opaque body portion; a transparent front portion; and an inspection flap folded under the f'transparent front portion of the envelop and frictionally held in folded position thereby,
